摘要：

The single-rung t-J ladder is analyzed in a mean-field theory using Gutzwiller renormalization of the matrix elements to account for strong correlation. The spin-liquid (resonance valence bond) state at half-filling evolves into a superconducting state upon doping. The order parameter has a modified d-wave character. A lattice of weakly coupled ladders should show a superconducting phase transition.
